Application filed December 19, 1919. Serial No.'345,990. I

7 To. all whom it may concern Be it known that I. ERNEST N. JOHNSON, a

subject of the King of Great Britain, of the city of Vinnepeg, in theProvince of Manitoba, Canada, have invented certain new and useful Improvements in Switch-Rails, of

' a simply constructed-easily operated, positive and easily installed switch rail which can be manipulated to connect intersecting tracks as occasionmay demand.

A further and important object of the invention is to construct the switch rail and operating mechanism therefor such that 513.15 positively locked againstmovement in both its limiting positions and which form entire function of carryin and directin the car wheel at the point of intersection ot the main line, turn out rail and the side rail with which it is directly associated.

A still further andovery important object of the invention is to arrange the switch rail and the operating and locking bars in a .lrnanner such that the entire action of unlocking the switch rail in one position, moving it to its limiting second position and subsequently locking it in such second position ican be accomplished in a single movement lin one direction of the controlling rod and by so doing entirely dispense with amultiplicity of operating actlons.

- h further object is to construct the ap 'pliance so that it is entirely weather proof and such that all the rails associated therewlt h are amply supported and ballasted.

:W 1th the above more important and other rninor objects in View, which will become rnore a parent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinmore particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which asjit ,ears installed.

In the drawings like characters of reference indicate corresponding parts in the several figures.

l and 2represent the usual main line rails,

.3 and 4 side rails and 5 the customary turn out rail passing angularly across between the mainline rails. All the rails are carried 'in the ordinary way by ties or sleepers 6.

. My switch rail is'installed instead of the customary frog which appears in the locationv where theturn out rail and inner side rail intersect the. main line rail 2 and by installthan plate 10. These plates form a bed plate not only for the switch rail but also for the adjacent ends of the main line, turn out and inner side rails. The meeting ends of the rails f2 and 3 are permanently riveted as indicated at 12 to a rail plate 13 Which is in turn permanentlyfastened by bolts 14 to the outer end of the plate 11 there being a space maintained between the plates 13 and 11 by inserted spacers 15 placed on the bolts.

The inner ends of the rails 2 and 5 WlllCll converge toward my switch are separated by a spacing block 16 fastened to the rails by horizontallydisposed bolts 17 passing through the rails and blocks. To the bases of these rails I permanently fasten as by rivets 18 the rail plate 19 which in turn is secured by bolts 20 to the entendlng end of the plate 10, spacers 21 being inserted between the rail and "end plates;

Here I wish it to be observed that the inner ends of the rails extend inwardly slightly beyond the rail plates to which they areattached and overhang the ends of apivoted ,topplate22 which is contarned witlnn theisamei wrizontal plane contain ng 26 real the topxpla'te. f rangement issuch that when the top'plate plates and which obviously is spaced from the endplates a fixed distance equal to the depth of the spacers 15 and 21. Thetop plate is pivotally fastened to the end plate being securely riveted to the'underside of the top plate while the under spacer is permanently riveted to the top' side of the end plate. The head of the king bolt is countersunk in the top plate so that it lies flush. The king bolt 23 is located a selected distance in from'the meeting ends of the rails 2 and 3 and the end of the top plate remote from the king pin is formed in an arc radial to the king pin as is'also the inner end of the rail plate 19.

The end of the top plate adjacent the king pin is'cut to allow of the free lateral swinging movement of the top plate a limited distance as required by the manipulation of the switch rail. On the top plate I mount a switch rail 26 which passes lengthwise of the plate and is-permanently secured thereto by clamping pieces 27 overhanging the base of the switch rail and fastened by bolts 28 to In actual practice'the aris moved to its limiting position in one direction the switch rail forms a through con-' nection'in the main rail 2 and such that when'it is turned to itslimiting position in the opposite direction the switch rail forms a through connection betweenthe turn out rail 5' and the inner side rail 3.

The mechanism for moving the plate will be later disclosed.

In the space between the base plate and the top plate I locate aturn plate 29 which is practically-half a disk and which is pivotally secured centrally by a pivot pin 30 to the top plate; The body of the disk is actually in the plane of the end plates and it is fitted with a boss 31 so that a space is reserved between the body of the disk and from the center pin 30. The free ends of the bolts extend toward the free end of the top plate and ride the'inner end of the end plate 10 and are held for parallel movement in and out by facial projections 37 cast on the under side of the top plate and providing guide slots 38 and 39 receiving the tion of a locking bar 43 lying between the top plate and the base plate. At the opposite sides of the locking bar and directly above the guide plates I secure permanently by rivets 44 to the top plate, push bars 45, 46 and 47, the bars 46 and 47 being parallel to that 45 and being spaced so that the upper part of the'locking bar is positively guided between them. I

A rocking lever 48 is pivotally connected by a pivot pin 49 tothe top plate and has the ends thereof slotted and receiving pivot pins 50 and 51 connecting it respectively to the turn plate and to the locking bar which it will be observed is notched away on the top side and centrally of its length to receive the end of the said lever. In the space between the top plate, end plate 10 and base plate 7 I locate a pair of upper filler plates 52 and 53 and a pair of under filler plates 54 and 55 which are securely riveted to the under plates and which act to prevent foreign material from lodging in the space oc-' videa locking opening or slot 56 adapted to receive one or other of the lockingbolts, dependingv on the shifted position of the switch rail. The slot is located centrally between the ends of the rails 3 and 5 and is closed at top and bottom by the overhanging end of the top plate andthe inner end of the end plate 10.

In constructing the parts I desire that the facial projections in striking the filler plates form a positive stop in the limiting positions for the top plate, such occurring when the locking bolt is directly alined with the slot. In order to accommodate the full movement of the top plate I have cut away the upper filler plate at 57. 7

To one end of the locking bar I connect pivotally an operating'bar 58 connected to the bell crank59 in turn connected'to an operating rod 60, the rod being under the direct control of the switch stand (not shown) and arranged so that in the manipulation of the rod 60 the locking bar can be shifted in or out as occasion may demand.

I wish now to refer to the guideway 42. (See Fig. 9.) The guide plate 40 has the opposite ends thereof presenting two curved faces 61 and 62 which are actually radial to the king pin 23 and between these two are like faces the edge of the guide plate presents two oppositely inclining faces 63 and 64 which meet at a central point 65. The

guide plate 41 presents two converging faces 66 and 67, the face'67 being parallel with the face 63 of theopposing bar while the face 66 is parallel with the face 64 of the bar 40.: The distance between the point 65 and the meeting point 68 of the converging faces 66 and 67 is practically the widthof theflocliihg barg the locjking bar actually sliding-between these points. rhe aching has is pi ovided with ame races and 76 ,which aie Ciit Oil a radius equal to theifadius oi the arcs 6'1 and 'QQE-aiid said-faces 69 aiid'm are designed in the movement tl eioehi g-ha to engage .Witliand ride th faces Grand e to betterunderstand the iiiveiit oii I will now describe the manner which it opertlte assilihlilg jihitlally the switch rail seas in the .tlir'ough'niaiii line phas s,

' that is; to-say it is; connecting with the,

through rail 2 and that in suchpositionof the parts ar in the position as shownin Fig-550i the draw'lngsjvhere it will be" observed that the locking ba'r' is iii stand initially pullingthe rod 60in the di-- its innermost position and the looking bolt 32 is lockln the top late against lateral movement. pen the operator at the switch rection indlcatedhy the arrow Fig. 1.he

' effe ts an initial short 'm vehiehtofthe 1 ing' bai in th direction indicated the applied arrow Fi'". 5 and he e it is to be ob= served that at t e 'start of the the curved face 69 is clearof the curved face 61 and that the locking bar is riding guided b the races 66 and 64:. Iii thefir'sjt initial movement of the locking bar which is a t mel end shifting; one the curved faces 59 and c1 aie brought together and da ing interval of this inoveinent the rocking lever bee jturhed to the position shown in dotted outline in Fig. 5 and has effected the unlocking fthe bolt 32, the bolts being then in the position as shown in d otted out- I I a a. line in Fig, 5, The switch rail 15; accord top plate and the locking bolt 33 is then. directly allned with the slot 56 and the other parts have theposition shown in full outline in Fig-6.

In this position of the bars the switch ra1l is making a through connection between the turn out rail 5 and the side rail 8. At

the timethe second locking bolt has beenv brought to locking position the facial pro- JBCtlOIl 37 has engaged with the'filler plate,

thereby positively limiting the movement in that direction. Once the locking bar has been brought to the position shown in Fig. 6 a further pull in the red 60 causes a straight end movement in the' locking bar- 'ter'the only time that the plate can move which eiiects the turning of the lever 48 and the consequent entrance of the lockinlg bolt 33 in the slot 56 with the final resu ih ly am abletc control the wl'ioleaetion of the switch ifall by one operating lever.-

VVhile I have fully described the oper'ation and actionof the locinng bar when moving ino'ne direction I wish it to be dis-- tinc'tly iiiiderstood that upon the locking bar being moved in the op o'site direction the action is duplicated, the heir; which is locked at the beginning of the movement bein first unlocked; then'the switch rail turns and finally the other bolt locked to positively fes the switch'rail against side movement. In this reverse action the faces 62 and 70' act in. the same manner as thefaces 61 and 69 previously described.

I desire not? to direct attention to the bar 43 which owing to" the peculiar arrange ment, ailords in itself sleek for the top plate. In considering this it will be seen that owing to the fact that the plate can nly swing Orr-the hing bolt as a fixed cen is when one or other f the faces 69] and 10c 79 of the bar is engaged with one or other oi the faces 61 and 62. In all other positions ndmovm'ent can occur in. the'plate as the locking bar is, in all other locations confined to a purely end shifting movement which is opposed to a movement in the arc of a circle centered on the king bolt.

Consequently the top plate carrying the switch rail can be entirely controlled by the locking bar without actually requiring the locking bolts, the locking bar initially loclring the plate against turning movement, than swinging it to set the switch rail and again locking it after the swinging movement has occurred.

Inrsuch an arrangement the projections 37 form a positive stop at the limitations to ofl'set lateral thrust at the free end of the switch rail in its limiting positions.

While I have described this invention and particularly the action of the locking bar for accommodating the unlocking of an element in one position, the moving of an ele- 'ment to another position and the subse- 7 parts to switch rail use as it could be utilized in a great many other mechanical contrivanc'es to do the same work in the single movement of a controlling lever; 7 What I claim as my invention is lfThe combination with a main line, a

turn out and a side rail, of a bed plate permanently secured to and supporting the aforesaid rails, a top plate pivotally secured to the bed plate and movable laterally be tween predetermined fixed limiting positions, 'a-movable rail inserted at the frog point permanently mounted on the top plate and designed-in one ofthe limiting positions of the bedplate to make a through main line rail connection and in the other of the limiting positions of the top plate to make a through connection betweenthe turn out and side rails, apair of locking bolts carried by the top plate and adapted alternately to lock the top plate against movement in its extreme positions of travel and reversible means for effecting in one controlling movement the initial unlocking of the locking bolt, the subsequent turning of the plate to its other limiting point of. travel and the final locking of the plate by the other of the boltsagainst movement in such latter position.
